Abstract
Two soybean crosses were examined for the estimation of heritability of agronomic characters and genetic correlations between characters. In F3 Iines derived from Kitami-shiro × Hon-Iku No.65, heritability of branching type expressed by ratio was very high, and genetic correlation between branching type and grain yield was high enough to select high yielders, namely, -0.799, indirectly through selection for branching type, In F3 Iines derived from Karikachi x Isuzu, genetic correlation between grain yield and total plant weight was also very high, namely, +0.869. Based on these results, signifi-cance of plant types in selection practices, possibility of selection for yield in early generations through plant types, and relation between grain yield and plant types were discussed
